• Errors while Cross compiling of ffmpeg for MIPS Openwrit

  6 octobre 2015, par goldenmean

  I am in process of cross-compiling ffmpeg for MIPS openwrt. I have built this cross-compilation toolchain myself from openwrt build-root.

  Now I am using that toolchain to cross compile ffmpeg. But the final step of build, linking is failing. Details below.

  The steps taken so far -

  1. ./configure of ffmpeg is done with correct cross-compilation options is successful

  2. There were some errors but after manually editing config.h , those were fixed.

  3. The compilation of libraries (libavformat, libavcodec,...) is successful

  4. Linking fails with error
     mips-openwrt-linux-uclibc-ld : cmdutils.o : undefined reference to symbol ’putchar’

  mips-openwrt-linux-uclibc-ld : note : ’putchar’ is defined in DSO /libc.so.0 so try adding it to the linker command line

  libc.so.0 : could not read symbols : Invalid operation

  make : *** [ffmpeg_g] Error 1

  I see that libc.so.0 is a sym link to libuClibc-0.9.33.2.so
  So then when I added this directory which has to LD_LIBRARY_PATH it gave all kinds of endianness mismatch errors like :

  pr : error while loading shared libraries : libpthread.so.0 : ELF file data encoding not little-endian

  Below is my ffmpeg configure command while cross-compiling ffmpeg -

• Build FFmpeg with Freetype2 for ARM

  28 avril 2016, par Pawel Cala

  I’m trying to build FFmpeg binary file with freetype library included ( I need it for drawtext filter ). Unfortunately I cannot configure ffmpeg properly and every try ends with "freetype not found" error.

  PS I’ve tried to build guardian-ffmpeg project but i’m getting errors during configure process.

  PS2 Building plain ffmpeg works perfectly well

  Configuration script :

  make distclean &./configure --target-os=linux \
  
  --cross-prefix=arm-linux-androideabi- \
  
  --arch=arm \
  
  --cpu=armv7-a \
  
  --enable-libfreetype --enable-filter=drawtext \ #!Freetype params
  
  --disable-network \
  
  --disable-ffplay \
  
  --disable-ffprobe \
  
  --disable-ffserver \
  
  --enable-protocol=file \
  
  --sysroot=${ANDROID_NDK_ROOT_PATH}/platforms/${ANDROID_API_VERSION}/arch-arm \
  
  --prefix=build/armeabi-v7a \
  
  --disable-asm \
  
  --extra-cflags='-DANDROID -Ifreetype2/ -I${ANDROID_NDK_ROOT_PATH}/sources/cxx-stl/system/include -march=armv7-a -mfloat-abi=softfp' \
  
  --extra-ldflags='-Wl,--fix-cortex-a8 -Lfreetype2/ -L../android-libs -Wl,-rpath-link,../android-libs' \
  
  --extra-cxxflags='-Wno-multichar -fno-exceptions -fno-rtti'
  
  make -j6 && make install || exit 0

  Directories sctructure :

  ffmpeg/
  
     -ffmpeg dirs/
  
     -freetype2/
  
     -rest of ffmpeg files ( including configure, make, etc )

  I’ve checked patch sources in guardian-project and I’ve found that ffmpeg configure file might need some changes in require_libfreetype method ?!

  Thanks in advance ( and sorry for my bad english )

  EDIT :
  Building on OSX Mavericks,
  Last 3 lines of config.log ; OSX hasn’t got pkg-config therefore false in 2nd line :

  require_libfreetype
  
  false --exists --print-errors freetype
  
  ERROR: freetype not found

  EDIT :
  SOLUTION !!!

  I’ve manadged to solve my issue. I’ve used Xubuntu 14.04 64bit + Freetype 2.5.3 + newest FFmpeg repo + install linux package "pkg_config" and small modifications in ffmpeg configure script ( find pkg_config and check initialization variable )
